Corrosion Resistant Marking

NLE’s Corrosion Resistant Process passes ASTM F1089-02 (Standard Test Method for Corrosion of Surgical Instruments) on 304, 316, 17-4 and 17-7 stainless steels!

Previously, a major disadvantage of laser marking or laser engraving in the medical industry was in the area of reusable, autoclaveable instruments made from 17-4 Stainless Steel. The laser process tended to cause the markings to corrode after several autoclave cycles.

Northeast Laser saw this as an opportunity to identify the cause and develop a solution to this challenging problem. The result (of over a year of research) is NLE’s proprietary Corrosion Resistant Process, which has proven effective on 304, 316, 17-4 and 17-7 stainless steels.

The 17-4 stainless steel slugs in the top photo were marked with NLE's proprietary Corrosion Resistant Process, while the slugs in the lower photo were marked with typical settings. Both sets of samples were subjected to 50 autoclave cycles, as well as the ASTM F1089-02 Boil Test and Copper Sulfate Corrosion Test. The results are quite dramatic. This proprietary process survives passivation and passes ASTM F1089-02 (Standard Test Method for Corrosion of Surgical Instruments) on 304, 316, 17-4 and 17-7 stainless steels both before and after passivating.
